Serial network interfaces reside on modular port adapters, which provide a direct connection between the high-speed bus in the router and the external networks. The PA-E3 provides a full-duplex synchronous serial E3 interface for transmitting and receiving data at rates of up to 34 megabits per second (Mbps).

The port adapter supports both 16- and 32-bit cyclic redundancy checks (CRCs). The default is 16-bitCRCs;toenable 32-bit CRCs, you use a conﬁguration command. For a description of the CRC function, see the “Conﬁguring Cyclic Redundancy Checks” section on page 8-10.

Note Although the VIP2 and Catalyst RSM/VIP2 supports online insertion and removal (OIR),

individual port adapters do not. To replace port adapters, you must ﬁrst remove the VIP2 and Catalyst RSM/VIP2 from the chassis, and then replace port adapters as required.

The Cisco 7100 series, Cisco 7200 series, and Cisco uBR7200 series routers support the OIR of all port adapter types.

PA-E3 Serial Port Adapter Installation and Configuration

After system initialization, the ENABLED LED goes on, indicating that the port adapter has been enabled for operation.

The following conditions must be met before the PA-E3 port adapter is enabled:

• The port adapter contains a valid microcode version that has been downloaded successfully.

• For Cisco 7000 and 7500 series routers, the port adapter is correctly connected to the VIP2 and

the midplane and is receiving power in the Cisco router.

• For the Catalyst 5000 family switches, the port adapter is correctly connected to the

Catalyst RSM/VIP2 and is receiving power in the switch.

• The bus recognizes the port adapter.

If any of these conditions are not met, or if the initialization fails for other reasons, the ENABLED LED does not go on.

PA-E3 Serial Port Adapter Installation and Configuration

Interoperability Guidelines for PA-E3 DSUs

On a single PA-E3, there are one or two serial E3 ports, each with two connectors (receive and transmit), where you connect the Cisco 75-ohm coaxial cable. The 75-ohm coaxial cable (Cisco part number CAB-ATM-DS3/E3) for the PA-E3 is available only from Cisco Systems; it is not available from outside commercial cable vendors.

The Cisco E3 75-ohm coaxial cable, which comes with an attached ferrite sleeve (see Figure 1-5), is available only in 10-foot (3.05-meter) lengths. The typical maximum distance between stations for E3 transmissions is 1300 feet (396 meters).

Note For E3 (75-ohm) connections, you must have ferrite beads on the 75-ohm coaxial cable and

EMI decoupling clips on the Rcvr end of the cable (see Figure 1-5) if compliance with European certiﬁcation standards for emission control is required (EN55022/CISPR22 Class B for radiated emission levels).

Caution

The VIP2 requires that the host Cisco 7000 series router have the RSP7000 and RSP7000CI installed. The VIP2 does not operate properly with the Route Processor (RP), Switch Processor (SP), or Silicon Switch Processor (SSP) installed in the host Cisco series router.

ThePA-E3 is considered a high-bandwidth port adapter; therefore at a minimum, Cisco recommends that the PA-E3 be installed on the VIP2-15 or Catalyst RSM/VIP2-15 motherboard (with 1 MB of SRAM and 8 MB of DRAM). Installation of the PA-E3 on the VIP2-10 (with 512 KB of SRAM and 8 MB of DRAM) is not recommended.

PA-E3 Serial Port Adapter Installation and Configuration

Safety Guidelines

Note The VIP2 and Catalyst RSM/VIP2 supports online insertion and removal (OIR), but

individual port adapters do not. To replace the port adapters, you must ﬁrst remove the VIP2 or Catalyst RSM/VIP2 from the chassis and then replace port adapters as required. OIR is supported for port adapters in the Cisco 7100 series, Cisco 7200 series, and Cisco uBR7200 series routers. Port adaptershavea handle attached, butthis handle is occasionally not shownin illustrations in this publication to allow a full view of detail on the port adapter’s faceplate.

In the Cisco 7000 series, Cisco 7100 series, Cisco 7500 series, Cisco uBR7200 series routers and Catalyst 5000 family switches, there are no restrictions on slot locations or sequence; however, in the Cisco 7200 series routers, there are speciﬁc conﬁguration guidelines that must be observed for high-bandwidth port adapters.

For speciﬁc Cisco 7200 series hardware conﬁguration information and for memory conﬁguration guidelines for Cisco 7200 series routers, refer to the document Cisco 7200 Series Port Adapter Hardware Conﬁguration Guidelines, which shipped with your Cisco 7200 series chassis and is also available on the Cisco Connection Documentation, Enterprise Series CD-ROM.

To determine if your Cisco 7000 series, Cisco 7100 series, Cisco 7500 series, Cisco 7200 series, or Cisco uBR7200series router,or the Catalyst RSM/VIP2 is compatible with the PA-E3,use theshow version command to display the current hardware conﬁguration of the router,including the system software version that is currently loaded and running.

You can check the version of the default ROM image by removing the board and checking the ROM labels, or by conﬁguring the interface or system software to boot from ROM, restarting the system, and using the show version command to check the running version.

To display the current system software version, use the show version command. In the following example, the running system software is Release 11.1(16)CA.

Varning! Denna varningssymbol signalerar fara. Du beﬁnner dig i en situation som kan leda till

personskada. Innan du utför arbete på någon utrustning måste du vara medveten om farorna med elkretsar och känna till vanligt förfarande för att förebygga skador. Se förklaringar av de varningar som förkommer i denna publikation i dokumentet Regulatory Compliance and Safety Information (Efterrättelse av föreskrifter och säkerhetsinformation), vilket medföljer denna anordning.

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedures requiring access to the chassis interior, locate the emergency

power-off switch for the room in which you are working.

• Disconnect all power and external cables before moving a chassis.

• Do not workalone when potentiallyhazardous conditions existand never assume that power has

been disconnected from a circuit; always check.

• Do not perform any action that creates a potential hazard to people or makes the equipment

unsafe. Carefully examine your work area for possible hazards such as moist ﬂoors, ungrounded power extension cables, and missing safety grounds.

Electrical Equipment Guidelines

Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is speciﬁcally designed for wet

locations.

• Never touch uninsulated telephone wires or terminals unless the telephone line has been

disconnected at the network interface.

• Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperlyhandled,resultsincompleteorintermittentfailures.Portadaptersandprocessormodules consist of printed circuit boards that are ﬁxed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.

The following are guidelines for preventing ESD damage:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

• Connect the equipment end of the strap to an unﬁnished chassis surface.

• When installing a component, use any available ejector levers or captive installation screws to

properly seat the bus connectors in the backplane or midplane. These devicesprevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.

• When removing a component, use any available ejector levers or captive installation screws to

release the bus connectors from the backplane or midplane.

Preparing for Installation 2-5

Compliance Information

• Handle carriers by available handles or edges only; avoid touching the printed circuit boards or

connectors.

• Place a removed component board-side-up on an antistatic surface or in a static shielding

container. If you plan to return the component to the factory, immediately place it in a static shielding container.

• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects

components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

• Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should

be between 1 and 10 megohms (Mohm).

Compliance Information

The following sections provide compliance information thatapplies to the FCC andthe PA-E3 serial port adapter, which has beendesigned to meet these requirements. Modiﬁcations to this product that are not authorized by Cisco Systems, Inc., could void the various approvals and negate your authority to operate the product.

BABT Compliance

The BABT607116 marking on the PA-E3 signiﬁes that it meets United Kingdom directive 607116 and has been designed to BABT standards. The BABT label is located on the top of the PA-E3; Figure 2-1 shows the BABT label for the PA-E3.

Figure 2-1 BABT Label for PA-E3 Serial Port Adapter

607116

ITI-T Compliance

ITI-T recommendation G.823 speciﬁes that it is important to restrict jitter gain. Figure 4 of G.823 shows a typical jitter transfer characteristic. (Note that small jitter gain is allowed.)British Standard 6328:Section 8.1 1990 givesthe allowablegain as 0.5 dB. The PA-E3’s line mode clocking complies with these sections.

TBR24 Compliance

WhenthePA-E3 is in line clocking mode, jitter is not attenuated, and any jitter receivedistransferred to the line. If input jitterexceedsthe limits of TBR24, then outputjitter will not meet TBR24 transfer speciﬁcations. Line clocking mode is intended for use only where the connection involves a single hop, and where clock timing will not be transferred to other network equipment.

Depending on the circumstances, you might need to install a new port adapter on a VIP2 motherboard or replacea failed port adapter in the ﬁeld. In either case, you need a number 1 Phillips screwdriver, an antistatic mat on which you can place the removed interface processor, and an antistatic container in which you can place a failed port adapter for shipment back to the factory.

Note The PA-E3 can be installed on a VIP2-15, VIP2-20, VIP2-40, or VIP2-50 motherboard;

however, installation on the VIP2-10 is not recommended.

Caution To prevent system problems, do not remove port adapters from the VIP2 motherboard or

attempt to install other port adapters on the VIP2 motherboard while the system is operating. To install or replace port adapters, ﬁrst remove the VIP2 from its interface processor slot.

Note Each port adapter circuit board is mounted to a metal carrier and is sensitive to ESD damage.

The following procedures should be performed by a Cisco-certiﬁed service provideronly.The VIP2 supports online insertion and removal (OIR), but individual port adapters do not. To replace port adapters, you must ﬁrst remove the VIP2 from the chassis and then install or replace port adapters as required. If a blank port adapter is installed on the VIP2 in which you want to install a new port adapter, you must ﬁrst remove the VIP2 from the chassis and then remove the blank port adapter.

VIP2 and the PA-E3 3-3

Removing a Port Adapter

When only one port adapter is installed on a VIP2, a blank port adapter must ﬁll the empty slot. This allows the VIP2 and router chassis to conform to electromagnetic interference (EMI) emissions requirements, and encourages air to ﬂow through the chassis properly. If you plan to install a new port adapter, you must ﬁrst remove the blank port adapter.

Removing a Port Adapter

Following is the standard procedure for removing any type of port adapter on the VIP2:

Step 1 Attach an ESD-preventive wrist strap between you and an unﬁnished chassis surface.

Note If you want to install a new port adapter on a VIP2 with a single port adapter, you

must ﬁrst remove the blank port adapter from the port adapter slot in which you want to install the new port adapter.

Step 2 Fora newport adapter installation or a portadapter replacement, disconnect any interface

cables from the ports on the front of the port adapter, although this is not required. You can remove VIP2s with cables attached; however, we do not recommend it.

Step 3 To remove the VIP2 from the chassis, follow the steps in the section “Removing a VIP2”

in the conﬁguration note Second-Generation Versatile Interface Processor (VIP2) Installation and Conﬁguration, which shipped with your VIP2. Place the removed VIP2

on an antistatic mat.

Step 4 Locate the screw at the rear of the port adapter (or blank port adapter) to be replaced.

(See Figure 3-3.) This screw secures the port adapter (or blank port adapter) to its slot.

Grasp the handle on the port adapter and pull the port adapter from the router midplane, about halfway out of its slot. If you are removing a blank port adapter, pull the blank port adapter completely out of the chassis slot.

Note As you disengage the port adapter from the midplane, OIR administratively shuts

down all active interfaces on the port adapter.

Step 4 With the port adapter halfway out of the slot, disconnect all cables from the port adapter. Step 5 After disconnecting the cables, pull the port adapter from its chassis slot.

Caution Always handle the port adapter by the carrier edges and handle; never touch the

port adapter’s components or connector pins. (See Figure 6-4.)

Step 6 Place the port adapter on an antistatic surface with its components facing upward, or in a

static shielding bag. If the port adapter will be returned to the factory, immediately place it in a static shielding bag.

This completes the procedure for removing a port adapter from a Cisco uBR7200 series router.

Installing a Port Adapter

Following is the procedure for installing a port adapter in a Cisco uBR7200 series router:

Step 1 Attach an ESD-preventive wrist strap between you and an unﬁnished chassis surface. Step 2 Use both hands to grasp the port adapter by its metal carrier edges and position the

port adapter so that its components are downward. (See Figure 6-4.)

Step 3 Align the left and the right edge of the port adapter metal carrier between the guides in

the port adapter slot. (See Figure 6-5.)

Depending on your circumstances, you might need to install a new port adapter in a Cisco 7100 seriesrouter or replace a failed port adapter in the ﬁeld. All port adapters available for the Cisco 7100 series connect directly to the router and are locked into position by a locking tab with two screws (see Figure 7-1 or Figure 7-2). You need a number 2 Phillips screwdriver to loosen the screws.

Note Cisco 7100 series routers support online insertion and removal (OIR); therefore, you do not

have to power down the router when removing and replacing a port adapter.

Removing a Port Adapter

Follow these steps to remove a port adapter from a Cisco 7100 series router:

Step 1 Attach an ESD-preventive wrist strap between you and the chassis. (See Figure 7-1 or

Figure 7-2 for the location of the ESD plug.)

Step 2 Use a number 2 Phillips screwdriver to loosen the screws on the locking tab; then slide

the tab down to the unlocked position. (See Figure 7-1 or Figure 7-2.)

Step 3 Grasp the handle on the port adapter and pull the port adapter from the router, about

halfway out of its slot. If you are removing a blank port adapter, pull the blank port adapter completely out of the chassis slot.

Note As you disengage the port adapter from the router, OIR administratively shuts

down all active interfaces on the port adapter.

Step 4 With the port adapter halfway out of the slot, disconnect all cables from the port adapter. Step 5 After disconnecting the cables, pull the port adapter from its chassis slot.

Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter’s

components or connector pins. (See Figure 7-3.)

Note The blank port adapter is available from Cisco Systems as a spare. The blank

port adapter product number is MAS-7100-PABLANK.

This completes the procedure for removing a port adapter from a Cisco 7100 series router.

Installing a Port Adapter

Follow these steps to install a new port adapter in a Cisco 7100 series router:

Step 1 Attach an ESD-preventive wrist strap between you and the chassis. (See Figure 7-1 for

the location of the ESD plug.)

Step 2 Ensure that the locking tab is down in the unlocked position. If it is locked, use a

number 2 Phillips to loosen the screws; then slide the tab down to the unlocked position. (See Figure 7-1.)

Step 3 Remove the new port adapter from its antistatic container and position it at the opening

of the slot.

Step 4 Use both hands to grasp the port adapter by its metal carrier edges, and position the port

adapter so that its components face downward. (See Figure 7-3.)

Step 5 Align the left and the right edge of the port adapter metal carrier between the guides in

the port adapter slot. (See Figure 7-4.)

Step 6 Withthe metal carrieraligned in the slot guides,gently slide the port adapterhalfway into

the slot.

Caution Do not slide the port adapter all the way into the slot until you have connected all required cables.

PA-E3 Serial Port Adapter Installation and Configuration

CHAPTER

Configuring the PA-E3 Interfaces

To continue your PA-E3 serial port adapter installation, you must conﬁgure the E3 interfaces. The instructions that follow apply to all supported platforms. Minor differences between the platforms are noted. This chapter contains the following sections:

• Using the EXEC Command Interpreter, page 8-1

• Identifying Port Adapter Slot and PA-E3 Interface Port Numbers, page 8-2

• Performing a Basic Conﬁguration, page 8-7

• Conﬁguration Example, page 8-8

• Customizing the PA-E3, page 8-8

• Conﬁguring Cyclic Redundancy Checks, page 8-10

• Checking the Conﬁguration, page 8-11

If you installed a newPA-E3 or if you want to change the conﬁguration of an existing interface, you must enter conﬁguration mode using the conﬁgure command. If you replaced a PA-E3 that was previously conﬁgured, the system recognizes the new PA-E3 interfaces and brings each of them up in their existing conﬁguration.

After you verify that the new PA-E3 is installed correctly (the enabled LED goes on), use the privileged-level conﬁgure command to conﬁgure the new interfaces. You will need the following information for your conﬁguration:

• Protocols you plan to route on each new interface

• Internet Protocol (IP) addresses if you are conﬁguring the interfaces for IP routing

• Plan to use bridging or not on the new interfaces

• Timing source for each new interface and clock speeds for external timing

For a summary of the conﬁguration options available and instructions for conﬁguring interfaces on the PA-E3, refer tothe appropriate conﬁguration publications listed in the “Related Documentation” section on page vi.

Using the EXEC Command Interpreter

You modify the conﬁguration of your router through the software command interpreter called the EXEC (also called enable mode). You must enter the privileged level of the EXEC command interpreter with the enablecommand before you can use the conﬁgure command to conﬁgure a new interface or to change the existing conﬁguration of an interface. The system prompts you for a password if one is set.

Configuring the PA-E3 Interfaces 8-1

Identifying Port Adapter Slot and PA-E3 Interface Port Numbers

The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, use the following procedure to enter the privileged level:

Step 1 At the user-levelEXEC prompt, enter the enable command. The EXEC prompts you for

a privileged-level password as follows:

Router> enable

Password:

Step 2 Enter the password (the password is case-sensitive). For security purposes, the password

is not displayed.

Step 3 When you enter the correct password, the system displays the privileged-level system

prompt (#):

Router#

Proceed to the following section to conﬁgure the new interfaces.

Identifying Port Adapter Slot and PA-E3 Interface Port Numbers

This section describes how to identify port adapter slot and PA-E3 interface port numbers for Cisco 7200 series routers, Cisco 7100 series routers, Cisco uBR7200 series routers, and the VIP2.

You can identify interface ports by physically checking the port location on the back of the router or by using softwarecommands to display information about a speciﬁc interface or all interfaces in the router.

The PA-E3 can be installed in the following slots on the hardware platforms described in this document:

• VIP2—Port adapter slot 0 and slot 1

• Catalyst RSM/VIP2—Port adapter slot 0 and slot 1

• Cisco 7100 series routers—Port adapter slot 3 in a Cisco 7120 series router and port adapter

slot 4 in a Cisco 7140 series router

• Cisco 7200 series routers—Port adapter slot 1 and slot 2 in a Cisco 7202; port adapter slot 1

through slot 4 in a Cisco 7204 and Cisco 7204VXR; port adapter slot 1 through slot 6 in a Cisco 7206 and Cisco 7206VXR

• Cisco uBR7200series—Port adapterslot 1 and slot 2 in a Cisco uBR7246 andport adapterslot 1

in a Cisco uBR7223

Port adapters have a handle attached, but this handle is occasionally not shown in this document to allow a full view of detail on the port adapter’s faceplate.

Cisco 7200 Series and Cisco uBR7200 Series Ports

Physical port addresses specify the actual physical location of each interface port on a Cisco 7200 series router (see Figure 8-1) or a Cisco uBR7200 series router (see Figure 8-2). This address is composed of a two-part number in the format port adapter slot number/interface port number, as follows:

8-2

• The ﬁrst number identiﬁes the chassis slot in which the PA-E3 is installed.

• The second number identiﬁes the interface port on each PA-E3; the interface port is always

numbered as interface 0 for the one-port PA-E3 and 0 or 1 for the two-port PA-2E3.

PA-E3 Serial Port Adapter Installation and Configuration

Cisco 7200 Series and Cisco uBR7200 Series Ports

Interface ports maintain the same address regardless of whether other port adapters are installed or removed from the slot. However, when you move a port adapter to a different slot, the ﬁrst number in the address changes to reﬂect the new chassis slot number.

In Cisco 7200 series routers, port adapter slots are numbered from the lower left to the upper right, beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202, slot 4 for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR. Port adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller if present. Figure 8-1 shows the port adapter slots and interface ports of a Cisco 7206. The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter.

Note The I/O controller is available with or without a Fast Ethernet port. You can install both I/O

controller types in all Cisco 7200 series routers; however, when you install an I/O controller with a Fast Ethernet port in a Cisco 7202, the system software automatically disables the port.

For example, the serial port on a one-port PA-E3 in port adapter slot 3 has the address 3/0. (See Figure 8-1.) If the PA-E3is in port adapter slot 1, this same interface port is numbered 1/0. The serial ports on a two-port PA-2E3 in port adapter slot 3 have the addresses 3/0 and 3/1.

Note The PA-E3 is considered a high-bandwidth port adapter; you must observe speciﬁc

conﬁguration guidelines. Refer to the publication Cisco 7200 Series Port Adapter Hardware Conﬁguration Guidelines, which shipped with your Cisco 7200 series chassis and is also available

on the Cisco Connection Documentation, Enterprise Series CD-ROM.

Port adapters can occupy any port adapter slot; there are no restrictions.

For example, the serial port on a one-port PA-E3 in port adapter slot 1 has the address 1/0. (See Figure 8-2.) If the PA-E3is in port adapter slot 2, this same interface port is numbered 2/0. The serial ports on a two-port PA-2E3 in port adapter slot 2 have the addresses 2/0 and 2/1.

VIP2 Ports

In the router, physical port addresses specify the actual physical location of each interface port on the router interface processor end. (See Figure 8-3.) Each address is composed of a three-part number in the format interface processor slot number/port adapter number/interface port number, as follows:

• The ﬁrst number identiﬁes the chassis slot in which the VIP2 is installed (as shownin the sample

system in Figure 8-3).

• The second number identiﬁes the physical port adapter slot on the VIP2, and is either 0 or 1.

• The third number identiﬁes the interface port on each E3 serial port adapter, which is always

numbered as interface 0 for the one-port PA-E3 and 0 or 1 for the two-port PA-2E3.

Note Although the processor slots in the 7-slot Cisco 7000 and Cisco 7507 and 13-slot Cisco 7513

are vertically oriented and the slots in the 5-slot Cisco 7010 and Cisco 7505 are horizontally oriented, all models use the same method for slot and port numbering.

Interface ports on the VIP2 maintain the same address regardless of whether other interface processors are installed or removed. However, when you move a VIP2 to a different slot, the ﬁrst number in the address changes to reﬂect the new chassis slot number.

Figure 8-3 shows the port adapter slots and interface ports of a sample Cisco 7505 system. On the VIP2, the ﬁrst port adapter slotnumber is always 0. The second portadapter slot number is always 1. The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter.

8-4

For example, the serial port on a one-port PA-E3 in the ﬁrst port adapter slot in chassis slot 3 is numbered 3/0/0. (See Figure 8-3.) If the PA-E3 is in port adapter slot 1, this same port is numbered 3/1/0. The serial ports on a two-port PA-2E3 in the ﬁrst port adapter slot in chassis slot 3 are numbered 3/0/0 and 3/0/1.

Port adapters can occupy either port adapter slot; there are no restrictions.

Cisco 7100 Series Ports

In the Cisco 7100 series routers, the slot number is the location in the chassis where the interface resides and the port number is the physical port. Interfaces in the Cisco IOS software are identiﬁed by a type, slot number, and port number. For example, serial 3/1 indicates port 1 on the serial port adapter in slot 3.

Slots in the Cisco 7120 series routersare numbered as shown in Figure 8-5. The ﬁxed LAN interface is slot 0, the ﬁxed WAN interface is slot 1, and the modular port adapter interface is slot 3. Slots 2 and 4 are not used on the Cisco 7120 series routers. Slot 5 is the service module.

However, you might need to enter conﬁguration commands, depending on the requirementsfor your system conﬁguration and theprotocols you plan to route on the interface. Perform the tasks in the following sections if you need to customize the PA-E3.

8-8

PA-E3 Serial Port Adapter Installation and Configuration

Setting the Bandwidth

In interface conﬁguration mode, reduce effective bandwidth (range of 22 to 34010 kilobits per second) by entering the dsu bandwidth conﬁguration subcommand, as in the following example:

router(config-if)# dsu bandwidth 16000

Use the no form of this command to return to the default, 34010.

Note The local port conﬁguration must match the remote port conﬁguration. For example, if you

reduce the effective bandwidth to 16000 on the local port, you must do the same on the remote port.

Deﬁning the DSU Mode

In interface conﬁguration mode, deﬁne the DSU interoperability mode by entering the dsu mode [0 | 1] conﬁguration subcommand, as in the following example:

router(config-if)# dsu mode 1

Use the no form of this command to return to the default, 0.

Setting the Bandwidth

Note The local port conﬁguration must match the remote port conﬁguration. For example, if you

deﬁne the DSU interoperability mode as 1 on the local port, you must do the same on the remote port. Youneed to know what type of DSU is at the remote port to ﬁnd out if it interoperates with the PA-E3. For E3 serial interfaces, specify mode 0 for connection from a PA-E3to another PA-E3 or a Digital Link DSU (DL3100). Specify mode 1 for connection from a PA-E3 to a Kentrox DSU.

Also refer to the “Interoperability Guidelines for PA-E3 DSUs” section on page 15 for information regarding DSU feature compatibilities.

Deﬁning Set Bit (National)

In interface conﬁguration mode, deﬁne set bit in G751 frame (national bit) by entering the national bit [0 | 1] conﬁguration subcommand, as in the following example:

router(config-if)# national bit 1

Use the no form of this command to return to the default, which is 0.

Enabling E3 Scrambling

In interface conﬁguration mode, enable E3 scrambling by entering the scramble conﬁguration subcommand, as in the following example:

router(config-if)# scramble

Use the no form of this command to restore the default value, which is disabled.

Note The local port conﬁguration must match the remote port conﬁguration. For example, if you

enable scrambling on the local port, you must do the same on the remote port.

Also refer to the “Interoperability Guidelines for PA-E3 DSUs” section on page 15 for information regarding DSU feature compatibilities.

Configuring the PA-E3 Interfaces 8-9

Configuring Cyclic Redundancy Checks

Specifying E3 Framing

In interface conﬁguration mode, specify E3 framing by entering the framing {g751 | bypass} conﬁguration subcommand, as in the following example:

router(config-if)# framing g751

Use the no form of this command to return to the default, which is G.751 framing.

Note If you use the bypass option, scrambling must be set to the default, disabled; the DSU mode

must be set to the default, 0; and the DSU bandwidth must be set to the default, 34010.

Setting the Cable Length

In interface conﬁguration mode, set the cable length (0 to 450 feet), as in the following example:

router(config-if)# cablelength 250

Use the no form of this command to return to the default, which is 10 feet.

Conﬁguring Cyclic Redundancy Checks

The PA-E3 uses a 16-bit cyclic redundancy check (CRC) by default; it also supports a 32-bit CRC. The CRC is an error-checking technique that uses a calculated numeric value to detect errors in

transmitteddata. The sender of a data frame divides the bits in the framemessage by apredetermined number to calculate a remainder or frame check sequence (FCS). Before sending the frame, the sender appends the FCS value to the message so that the frame contents are exactly divisible by the predetermined number. The receiver divides the frame contents by the same predetermined number that the sender used to calculate the FCS. If the result is not 0, the receiver assumes that a transmission error occurred and sends a request to the sender to resend the frame.

Note To enable a 32-bit CRC on an interface, follow Step 1 and Step 2 of the preceding procedure

(enter conﬁguration mode and specify the slot and port address of the PA-E3, and the interface port number for a VIP2), and then enter the command crc 32. Enter Ctrl-Z to exit from conﬁguration mode.

For a Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series router, use the following example:

router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# router(config)# interface serial 3/0 router(config-int)# crc 32

Ctrl-z

8-10

PA-E3 Serial Port Adapter Installation and Configuration

Checking the Configuration

For a VIP2, use the following example:

router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# router(config)# interface serial 1/0/0 router(config-if)# crc 32

Ctrl-z

For a Catalyst RSM/VIP2, use the following example:

router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# router(config)# interface serial 0/0 router(config-if)# crc 32

Ctrl-z

To disable CRC-32 and return to the default CRC-16 setting, specify the slot and port address (and the interface port number for a VIP2) and use the no crc 32 command. For complete command descriptions and instructions, refer to the related software documentation.

Note When enabling a 32-bit CRC on an interface, ensure that the remote device is also conﬁgured

for a 32-bit CRC. Both the sender and the receiver must use the same CRC setting.

To check the interface conﬁguration using show commands, proceed to the following section, “Checking the Conﬁguration.”

Checking the Conﬁguration

After conﬁguring the new interface, use the show commands to display the status of the new interface or all interfaces, the ping command to check connectivity, and the loopback command to verify the physical interface.

Using show Commands to Verify Status

Use show commands to verify that the new interfaces are conﬁgured and operating correctly:

Step 1 Use the show version command to display the system hardware conﬁguration. Ensure

that the list includes the new interfaces.

Step 2 Display all of the current port adapters and their interfaces with the show controllers

command. Verify that the new PA-E3 appears in the correct slot.

Step 3 Specify one of the new interfaces as follows:

• showinterfacestype slot/port command on Cisco 7100 series, Cisco 7200 series,and

Cisco uBR7200 series routers

• show interfaces type slot/port-adapter/port on the VIP2

• show interfaces port-adapter/port on the Catalyst RSM/VIP2

Verify that the ﬁrst line of the display speciﬁes the interface with the correct slot number and that the interface and line protocol are in the correct state: up or down.

Configuring the PA-E3 Interfaces 8-11

Checking the Configuration

Step 4 Specify one of the new interfaces as follows:

Step 5 View the information that is speciﬁc to the serial interface hardware:

• show interfaces port adapter type slot/port on Cisco 7100 series, Cisco 7200 series,

and Cisco uBR7200 series routers

• show interfaces type slot/port adapter/interface command on the VIP2

• show interfaces port adapter/interface command on the Catalyst RSM/VIP2

Verify that the ﬁrst line of the display speciﬁes the interface with the correct slot number and that the interface and line protocol are in the correct state: up or down.

• For Cisco 7100, Cisco 7200 series and Cisco uBR7200 series routers, specify the new

serial interface with the show controllers serial [port adapter slot number/interface port number] command, and verify that the ﬁrst line of the display speciﬁes the interface with the correct slot number.

• For a VIP2, specify information that is speciﬁc to the new serial interface with the

show controllers serial [type slot/port adapter/interface] command, and verify that the ﬁrst line of the display speciﬁes the interface with the correct slot number.

• For a Catalyst RSM/VIP2, specify information that is speciﬁc to the new serial

interface with the show controllers serial [port adapter/interface] command, and verify that the ﬁrst line of the display speciﬁes the interface with the correct slot number.

Step 6 Display the protocols conﬁgured for the entire system and for the speciﬁc interfaceswith

the show protocols command. If necessary, return to conﬁguration mode to add or remove protocol routing on the system or on speciﬁc interfaces.

Step 7 Display the running conﬁguration ﬁle with the show running-conﬁg command. Display

the conﬁguration stored in NVRAM using the show startup-conﬁg command. Verify that the conﬁguration is accurate for the system and each interface.

If the interface is down and you conﬁgured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the network interface is properly connected and terminated. If you still have problems bringing the interface up, ask a service representative for assistance.

Using show Commands to Display Interface and System Information

For Cisco 7100, Cisco 7200, or Cisco uBR7200 series routers, to display information about a speciﬁc interface, use the show interfaces command with the interface type and port address in the format show interfaces type slot/port.

For Cisco 7100, Cisco 7200, and Cisco uBR7200 series routers, use the show controllers serial command, using arguments such as the slot and port number (slot/port), to display information that is speciﬁc to the serial interface hardware. Following is an example of the show controllers serial slot/port command that shows the serial port adapter installed on a Cisco 7200 series router in chassis slot 3:

router# show controllers serial 3/0

M1T-Serial: show controller: PAS unit 0, subunit 0, f/w version 1-23, rev ID 0x1, version 2 idb = 0x608E3340, ds = 0x608E50C0, ssb=0x608E5A84 Clock mux=0x35, ucmd_ctrl=0x8, port_status=0x25 maxdgram=4474, bufpool=64Kb, 128 particles TM=down CA=up LC=down line state: up Serial DTE cable (Display text omitted.)

For a VIP2, use the show controllers serial command, using arguments such as those that specify the slot, port adapter, and port numbers (slot/port-adapter/port), to display information that is speciﬁc to the serial interface hardware. Following is an example of the show controllers serial slot/port adapter/interface command that shows serial port 2/0/1 on a one-port PA-E3installed on a VIP2 in chassis slot 1:

Note The slot values displayed by some commands (such as show diag and show controllers

cbus) are not relevant to any physical connection; please disregard these slot values for the

Catalyst RSM/VIP2.

For complete command descriptions and examples for the Cisco 7100 series routers, Cisco 7200 series routers, Cisco uBR7200 series routers, the VIP2, and the Catalyst RSM/VIP2, refer to the publications listed in the “Related Documentation” section on page vi.

Using the ping Command to Verify Network Connection

The ping command allows you to verify that an interface port is functioning properly and to check the path between a speciﬁc port and connected devices at various locations on the network. For example, after you verify that the system and VIP2 have booted successfully and are operational, you can use the ping command to verify the status of interface ports. Refer to the publications listed in the “Related Documentation” section on page vi for detailed command descriptions and examples.

The ping command sends an echo request out to a remote device at an IP address that you specify. After sending a series of signals, the command waits a speciﬁed time for the remote device to echo the signals. Each returned signal is displayed as an exclamation point (!) on the console terminal;

Configuring the PA-E3 Interfaces 8-19

Checking the Configuration

each signal that is not returned before the speciﬁed timeout is displayed as a period (.). A series of

exclamationpoints (!!!!!) indicates a good connection;a series of periods (.....) or the message [timed

out] or [failed] indicates that the connection failed. Followingis an exampleof a successful ping command to a remote server with the address 10.0.0.0:

router# ping 10.0.0.0 <Return> Type escape sequence to abort. Sending 5, 100-byte ICMP Echoes to 1.1.1.10, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms router#

If the connection fails, verify that you have the correct IP address for the server and that the server is active(poweredon), andrepeat the ping command. Referto the publications listed inthe “Related Documentation” section on page vi for complete descriptions of interface subcommands and the conﬁguration options available for VIP2-related interfaces, and to determine which subcommands and conﬁguration options support VIP2 functionality.

Using the loopback Command to Verify the Physical Interface

Use the loopback {dte | local | network {line | payload} command to troubleshoot the E3 serial port adapter at the physical interface level. The command loops all packets from the E3 interface either back to the interface or from the network back out towardthe network. Use the no form of the command to remove the loop.

Thefollowingexamples of the loopback {dte| local |network {line | payload} commandconﬁgure loopback modes on the single interface (interface 0) of a one-port E3 serial port adapter in port adapter slot 0 of a VIP2 in chassis slot 10 of a Cisco 7500 series router:

• Set the interface into loopback data terminal equipment (DTE) mode as follows:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# interface serial 10/0/0 router(config-if)# loopback dte

Loopback DTE loops the router output data back toward the router (after the line interface unit).

• Set the interface into local loopback mode as follows:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# interface serial 10/0/0 router(config-if)# loopback local

Local loopback loops the router output data back toward the router at the framer.

• Set the interface into network line loopback mode as follows:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# interface serial 10/0/0 router(config-if)# loopback network line

Network line loopback loops the data back toward the network (before the framer).

Using the loopback Command to Verify the Physical Interface

• Set the interface into network payload loopback mode as follows:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# interface serial 10/0/0 router(config-if)# loopback network payload

Network payload loopback loops just the payload data back towardthe network at the E3 framer.
